About sound design
Sound design is the craft of creating, manipulating and assembling audio elements that aren't music or dialogue. It encompasses everything from the whoosh of a spaceship to the creak of a door, the interface beeps in an app, or the layered ambience that makes a forest scene feel alive. The work appears in film, television, games, theatre, podcasts, advertising, installations and any medium where sound shapes the experience.
Doing it well means building audio that serves the story or function without drawing attention to itself unless that's the intent. A poorly designed sound feels generic, mistimed, or tonally wrong—a laser blast that sounds like a cap gun, or footsteps that don't match the surface. Strong sound design feels inevitable: the audience believes the world because the audio supports every visual and emotional cue. This requires both technical skill—editing, layering, processing, synthesis—and a sense of narrative or spatial logic.
The process typically begins with spotting: identifying where sound is needed and what role it plays. Designers then source or create raw material through field recording, Foley performance, synthesis, or sample libraries, then shape and sequence those elements in a digital audio workstation. Final deliverables are usually stems or layered tracks that integrate with dialogue and music in the final mix, formatted to match the project's technical specifications.

Sound Design — questions and answers
- What's the difference between Foley and sound effects?
- Foley refers to everyday sounds performed and recorded in sync with picture—footsteps, clothing rustle, prop handling—usually captured on a Foley stage with specific surfaces and props. Sound effects are pre-recorded or synthesised elements like explosions, vehicles, or ambiences, edited and placed in post-production. Foley adds organic, synchronised detail; effects provide elements impractical or impossible to perform live.
- How do sound designers create sounds for things that don't exist in real life?
- Designers combine and process real-world recordings in unexpected ways: a lightsaber hum might blend a film projector motor with interference from a television tube. Synthesis generates tones and textures from scratch. Layering, pitch-shifting, time-stretching, convolution and granular processing turn mundane sources—metal scrapes, animal calls, kitchen utensils—into alien technology, creatures or abstract sonic events that feel believable within the world's rules.
- Why do sound designers deliver stems instead of a single mixed file?
- Stems are grouped submixes—backgrounds, hard effects, Foley, designed elements—that preserve flexibility for the final mix. The re-recording mixer balances sound design against dialogue and music, adjusts levels for different deliverables, or creates alternate versions for foreign language tracks. A single stereo file locks everything together, removing the ability to adjust individual layers or replace elements without starting over.
- Can sound design created for film be reused in a game or interactive project?
- Linear film sound is edited to precise timings and mixed into a fixed sequence. Games require modular, loopable or triggerable assets that respond to player actions, often with multiple variations to avoid repetition. The raw recordings might transfer, but the structure, file organisation and implementation differ entirely. Interactive sound also demands different technical specs, like lower latency and smaller file sizes for real-time playback.
- What does it mean to design in surround or immersive formats like Atmos?
- Surround formats place sound in a three-dimensional space using multiple speaker channels or objects. Instead of left-right stereo, designers position elements around and above the listener. This requires panning in spherical coordinates, considering how sound moves through space, and delivering files as multichannel beds or object-based metadata. The same source material gets spatially reimagined, not just spread across more speakers.
- How does sound design differ between naturalistic drama and stylised or abstract projects?
- Naturalistic work prioritises realism and spatial accuracy: a door sounds like the door on screen, ambiences match the location. Stylised or abstract design uses sound emotionally or conceptually—exaggerating, omitting or inventing elements to convey psychological states or thematic ideas. The technical process remains similar, but creative choices shift from mimicking reality to constructing a sonic language that supports tone, mood or metaphor over literal representation.
